GB/T 39546-2020 Equipment for crop protection—Knapsack motorized air-assisted sprayers—Test methods and performance limits

Scope: This standard specifies the technical requirements, test methods and minimum performance limits for knapsack air-fed (two-phase flow) sprayers and air-fed centrifugal sprayers (see ISO5681 definition). This standard applies to knapsack power sprayers (hereinafter referred to as sprayers) equipped with engines and carried by the operator, mainly for agriculture and gardening. This standard does not apply to hydraulic sprayers, thermal sprayers, room temperature foggers, or sprayers for spraying dry substances. This standard deals with the droplet deposition potential of sprayers under general technical conditions as well as under specified conditions. This standard does not include the safety content of the operator using the sprayer. See ISO28139 for safety requirements.
